Additional log on may be required - Windows Update

Introduction

Windows Update created a problem of constant popups stating that "Additional log on information may be required". The problem stems from Update KB2750841.

There are two possible fixes.
1. A registry change. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\NlaSvc\Parameters\Internet
Change EnableActiveProbing value to "0"
or
2. Uninstall the update causing the problem.

The American scientist Paul Ehrlich once said, "To err is human, but to really foul things up you need a computer." At risk of hyperbole, it is my humble opinion that a greater truth has never been uttered.
